X P4c is a professional compable intelligent charger, which is
compable with 14500/14650/16340/17500/17670/18350/
18500/18650/18700/22650/25500/26650 3.6V/3.7V rechargeable
lithium-ion baeries and AAA/AA/A/SC/C rechargeable Ni-MH
baeries.
Xp4c has the baery-type recognion feature-based on the baery
type, the charger could choose the different charge method
automacally. For 3.6V/3.7V lithium-ion baeries, XP4c adopts
three-phase charge method (TC, CC, CV); for Ni-MH baeries, XP4c
has the trickle charge and pulse charge plus the 0△V、-△V
detecon method, over-voltage protecon and stopping charging
when overme as well. Four slots are independent and no effect for
any other slot with real-me display of baery status and intelligently
charging.
For the memory effect of Ni-MH baeries, XP4c's CH1 slot has the
specialized discharge funcon that intelligently helps to repair the
baery capacity.

The XP4c uses a high efficiency DC - DC step-down circuit,
which can greatly reduce energy loss while resulng in a more
reliable, safer, and efficient charger. In addion, the XP4c
provides reverse-polarity and short-circuit protecon.
①
Two charge current opons (4*0.5A、2*1.0A) allow you to
choose a suitable charge current to balance charge me and
baery lifespan. The XP4c uses a so-start funcon, to avoid
damage from large charging currents when charging starts.
In addion, the X P4c has acvaon funcon, which helps to
repair the over-discharged baeries.
Note ① : Please take the Intelligent charge current parameter form as
reference.

Connect the supplied power adaptor to the XP4C. The XP4c
performs a self-check, meanwhile, charge current indicators
are all blue on, charging indicators are all red on. Aer the self-
check, all charging indicators are green on, 0.5A (default charge
current) gear indicator is blue on, the charger switches to
standby.
Insert your baeries into charging channels according to your
baeries type, which can take the above Intelligent charge
current parameter form as reference. Then the corresponding
charging indicators are blue on.
Note: Damage can occur to the batteries and charger if improper
batteries and charge current are selected.
CHARGING BATTERIES
Please charge compable baeries with X P4c.
Aempng to charge other baery types may be
hazardous, and can damage the baeries and charger.
XP4c is also compable with Ni-Cd baeries.
Only XP4c’s CH1 has the discharging baeries funcon
and is only suitable for Ni-MH/ Ni-Cd baeries; Do not
discharge for lithium-ion baeries.
XP4c has integrated short-circuit protecon to protect the
charger if a short circuit occurs in a baery. Note that this
short-circuit protecon protects the charger; it does not
prevent baeries from short-circuing internally.
Baeries can be hazardous-never leave charging cells
unaended, and remove baeries form charger once
charging cycle has finished.
Keep the XP4c away from water and excessive dust.
Do not disassemble the XP4c. Damage may result.
▏1 1
The XP4c provides two charge current opons. You can
insert baeries into different channels according the
intelligent charge current parameter to achieve different
charge speeds, but remember that faster charging may
reduce baery lifespan. Ensure safely charging and prolong
the baery lifespan, please take manual as reference.
If this manual descripon has differences with the official
website, please refers to official website.
TIPS
▏1 2 ▏1 3
▏0 8 ▏0 9
When the baeries are fully charged, the corresponding
charge indicators are green on, and then you could
remove the baeries.
Choose the charge current that best suits your 3.6 /3.7V
rechargeable lithium-ion baeries or Ni-MH baeries:
"0.5A": best for those lithium-ion baeries and AA /A Ni-
MH baeries whose capacity is equal or lower than
2500mAh.
"1.0A": best for those lithium-ion baeries and A/SC/C
Ni-MH baeries whose capacity is above 2500mAh.
For the lithium-ion baeries, all channels adopt so-start
funcon to avoid damage from large charging currents
when reviving over-discharged baeries. When the
lithium-ion baeries are fully charged, the X P4c stops
charging, and the corresponding LED turn green. It is
recommended that you remove baeries from the
charger once charging has completed. If lithium-ion
baeries are le in the charger aer charging completes,
the charger will automacally restart the charge cycle
when the voltage drops below 3.9 V.
DISCHARGING BATTERIES
▏0 5
For Ni-MH baery, using XP4c’s CH1 slot to discharge baery
to repair the capacity and eliminate the memory effect is
recommended. When the XP4C is in standby status, aer the
Ni-MH baery is put into the CH1 slot correctly, remove
baery when charge indicator is red on. Within three
seconds aer the green light on(the system will be default as
charging funcon starts if it’s over three seconds), reinsert
the baery, charge indicator red and green shiing flashes
and the baery is being discharged. When the baery
voltage reaches to 1.0V, XP4c starts the charging process
automacally.
NOTICE
X P4c is compatible with four 14500/14650/16340/17500/
17670/18350/18500/18650/18700 3.6V/3.7V rechargeable
lithium-ion batteries and four AAA/AA/A rechargeable Ni-MH
batteries. 22650/25500/26650 3.6V/3.7V lithium ion batteries and
USAGE
